    Subject[PATCH 0/3] Add version macros for clang and fix arm64 for clang <6.0
    Date
    In order to build an arm64 kernel with clang <6.0, we need to work
    around LLVM bug 30792 by using -mno-implicit-float instead of
    -mgeneral-regs-only.

    This patch set adds macros for checking clang version, and enable the
    workaround only for affected compiler versions.

    Greg Hackmann (1):
    arm64: use -mno-implicit-float instead of -mgeneral-regs-only

    Sami Tolvanen (2):
    kbuild: add clang-version.sh
    kbuild: add cc-if-name-version and compiler-specific variants

    arch/arm64/Makefile | 5 ++++-
    scripts/Kbuild.include | 31 +++++++++++++++++++++++++++++++
    scripts/clang-version.sh | 33 +++++++++++++++++++++++++++++++++
